Answer:
Modified apocrine sweat glands
Explanation:
The ceruminous glands are similar to sebaceous glands, belonging to the group of sweat glands. These glands secrete a sticky material, the ear wax, that protects the thin skin lining the ear canal.
As soon as a dust, dirt or an insect enters the ear canal at the beginning of the ear wax, the wax retains, wraps and pushes it outside the ear canal.
This secretion is lubricating as well as acidic, which helps to kill potentially harmful bacteria and fungi in the ears.
